While in this particular case it would indeed make things easier, it would be harder to support different operating systems. Here, Linux require two partitions (root fs + EFI or BIOS boot (*)), but other OSes have different requirements - for example Windows. Having different (number of) disks depending on OS installed inside would greatly complicate things. Here we treat content of root.img as a black box from dom0 point of view. See that the issue is about qubes.ResizeDisk service running inside of the VM, which can be implemented differently depending on operating system. (*) We have both to ease migration between those two modes, without the need to repartition root volume. - -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab A: Because it messes up the order in which people normally read text.
